_______________________________________________________
Details:
This bug report applies to avr-libc 1.8.1.
The documentation for time.h mentions the following:
Section 7.23.2.3 mktime() The standard specifies that mktime() should return
(time_t) -1, if the time cannot be represented. This implementation always
returns a 'best effort' representation.
Please explain what "best effort" means in this context, and also add relevant
information to the documentation of mktime and gm_mktime.
I assume these two functions clamp the value of the returned time_t to
[0,UINT32_MAX], but is that the only limitation?
